I looked around the site just to let 9810 owners know 7.0.0.439 is out Official from Wind Mobile Canada.
I've already installed it.
Runs great!!

this is an update as I realized that RIM has pulled 7.0.0.439 from their servers, as there were outstanding bugs not yet resolved.
The more I used 7.0.0.439, I realized this build has flaws, one for example, is I am unable to attach pictures to BBM contacts, and other minor issues I'm sure, so I won't recommend this build anymore.
